World Championships are sailed with supplied equipment; everywhere else a "home-built" boom is illegal as well.Don't bring your boom to a world championship; everywhere else you'll be fine.
Master worlds are not sailed with supplied boats. Showing up with a home built boom at a master worlds might cause you problems. I doubt you would have any problems anywhere else.World Championships are sailed with supplied equipment; everywhere else a "home-built" boom is illegal as well.
If you can't get real sleeves (PSA Sailing in Australia might actually have them), get new booms. If the boats will be used for recreational sailing only, then forget the whole thing. You won't need to sail as fast as someone with a stiffer boom. If they break, then get new ones.

Masters Worlds are sailed mostly with chartered boats, especially if they're outside Europe. Any illegal equipment should cause problems everywhere where you're racing. I find it troubling that we're even trying to find a certain level where at least certain class rules don't supposedly matter.Master worlds are not sailed with supplied boats.

You can think of it this way: the first 100,000 (or so) Laser booms were sleeveless. The class was thriving at the time and everyone was happy. Did a majority of those booms break? Of course not, just a big enough percentage to warrant a simple upgrade.You don't need a sleeve to be faster, but to prevent your boom from breaking. And w/o a sleeve it will break

That is incorrect in two ways. First, there is no "extra" force on the boom. If your leech tension/mast bend is the same (which is what you're aiming for), it doesn't matter how much purchase the system has - more of it merely makes the goal easier to achieve. The loads within the rig are identical.I have always heard the boom sleeve was added to accomodate the extra force applied to the boom by the new vang.
